Hello, please excuse my ignorance. I'm new to CNC's and have a basic electronics and software background.
I just purchase an SXCNC 6040 (JP-3163B v3.9) and can't get any movement from it.
I've tried aevery pinout combination I can find without any luck. The drivers do seem to be engaged while the machine is on, but I can't get any responses. I can tell my PCI parport card is getting something though as if I don't have the e stop inverted, I can't get LinuxCNC to be enabled.
I'm sure calibration is not entirely accurate, but I can go about correcting that once I can get some response. Any assistance or suggestions on things to check is greatly appreciated.

Have you tried to use the inverted signal:
You can use HALSHOW from the menu to check your signals in real time.
net estop-ext <= parport.0.pin-10-in-not

Thanks. I have tried inverted for the eStop (which I seems to be correct now) and for the X/Y/Z Step/Direction configuration without any luck.
Is there any way I can bypass the software altogether and send a command to move x or y just to make sure the hardware is good? I'd hook up a multimeter to the cable and check what I'm getting, but I'm not even confident enough to know what I should be getting.

# these are in nanoseconds
DIRSETUP = 10000
DIRHOLD = 10000
STEPLEN = 5000
STEPSPACE = 5000
See if that looks the same for every joint/axis in the ini file, if not make them same.

Thanks,
Looking through my ini, I'm not seeing any of those values being set for the joints or axis.
Is there somewhere I can set them globally, or should I manually add those values to each joint/axis?

I've set them in several places, and still no luck.

I think you have them set in the hal file and the ini file. They should only be set in one of them
In the hal file it seems you have them set at 50000. I think that should be 5000

Thanks for taking a look Clive. I just updated to 5000 in the hal file and still no luck unfortunately.

So I've been testing the parallel port direction pin values through a multi meter, and they don't appear to be changing as they should. I've tried both 0 and 0x378 as my port as it appears to be, but no luck.

Well, that certainly looks like 0 or 0x378 should both work.
It might be worth checking that all the pins in your parallel port cable are connected through.
